Abstract (en)
[origin: EP3778808A1] The present invention provides a copolymer for an antifouling coating composition which can realize an excellent antifouling performance for a long time even in a bay where adhesion of fouling organisms is extremely severe and which can form an antifouling coating film with excellent seawater resistance. According to the present invention, an antifouling coating composition, comprising: a copolymer P; and an antifouling agent; wherein: the copolymer P is a copolymer of a monomer (a), a monomer (b), a monomer (c), and an ethylenically unsaturated monomer (d) other than the monomers (a) to (c); the monomer (a) is represented by general formula (1);in the general formula (1), R<sup>1</sup> is a methyl group, R<sup>2</sup>, R<sup>3</sup>, and R<sup>4</sup> are the same or different, and each represents a C3-C8 branched alkyl group or a phenyl group; content of the monomer (a) is 25 to 50mass% with respect to a total mass of the monomers (a) to (d); each of the monomer (b) and (c) is a monomer having a common logarithm log P of n-octanol/water partition coefficient P of 0.00 to 0.59 and 0.60 to 0.95; the monomer (c) is a monomer having only one unsaturated bond is provided.
